Scientists with NASA’s Operation IceBridge released the original.

New photos of a surprisingly rectangular iceberg are offering the full picture of this now-known Antarctic structure. photo last week, but it only showed a portion of the odd iceberg.

With much of the ‘mountain out of the frame, it was not clear how geometric the whole structure really was. Now, new photos released by IceBridge scientists reveal the iceberg’s true shape.

These photos were captured by IceBridge senior support scientist Jeremy Harbeck, who spotted the table iceberg near the Larsen C ice shelf. Tabular icebergs are the products of calving ice shelves-when large chunks of ice suddenly break loose-and they are known for their highly angular lines and smooth tops.

Giuliani's remarks were an attempt to damage the control of comments he made one day…

“I thought it was pretty interesting,” said Harbeck in a NASA statement. “I often see icebergs with relatively straight edges, but I’ve not really seen one before with two corners at such right angles like this one had.”

In July 2017, Antarctica’s Larsen C ice shelf released the enormous A68 iceberg, which weighs about 1,000 billion tons and occupies an area roughly the size of the state of Delaware. Harbeck and his colleagues were investigating this massive structure when the geometric shape was spotted.

“I was actually more interested in capturing the A68 iceberg that we were about to fly over, but I thought this rectangular iceberg was visually interesting and fairly photogenic, so on a lark, I just took a few photos,” Harbeck said .

Interestingly, Harbeck spotted a second rectangular iceberg during the same October 16, 2018 flyby. In the photo above, you can actually see three icebergs of note: the now-famous freakishly geometric iceberg at far left (slightly obscured by the aircraft’s engines), the new table iceberg, and off to the horizon, the A68 iceberg. Yes, it’s that huge-the expanse along the horizon line is a free-floating iceberg measuring about 100 miles (60 miles) in length and about 30 miles (18 miles) wide).

Here are some other photos of table icebergs, many of which were produced by the Larsen C ice shelf during the A68 calving event.
